Title: New pesticidal ester salts of phosphorothiolothionic acid
Inventor: GHOSH RANAJIT
IPC: C07F9/165
Filed: 1955-03-30
Abstract: The invention comprises acid addition salts of phosphorothiolothionic esters of the formula S=P(OR1)(OR2)-S-LX wherein R1 and R2 are alkyl radicals, L is a saturated aliphatic hydrocarbon radical in which the carbon atoms may be interrupted by an oxygen atom, a sulphur atom or an N-Alkyl substituent, and X represents a salt of a secondary aliphatic or heterocyclic amino radical attached to L through the amine nitrogen atom, said nitrogen atom not being attached to the same carbon atom as the sulphur atom linking L with the phosphorus atom.  The compounds are prepared by reacting the corresponding bases of the above general formula with an appropriate acid.  The examples describe the preparation of the hydrochlorides, hydrogen oxalates and para-toluenesulphonates of O:O1-diethyl S-b -diethylaminoethyl phosphorothiolothionate, O:O1-diethyl S - 1 - di - n - propylaminoprop - 2 - yl phosphorothiolothionate, O:O1 - diethyl S - 1 - diethylaminoprop - 2 - yl phosphorothiolothionate, O:O1-diethyl S - b  - di - n - butylaminoethyl phosphorothiolothionate, O:O1 - diethyl S - b  - piperidinoethyl phosphorothiolothionate, O:O1-diethyl S - 1 - diethylamino - 3 - ethoxyprop - 2 - yl phosphorothiolothionate, O:O1-diethyl S-b -di - n - propylaminoethyl phosphorothiolothionate, O:O1 - diethyl S - 3 - diethylaminopropyl phosphorothiolothionate, O:O1 - di - n - propyl S - b  - diethylaminoethyl phosphorothiolothionate, O:O1 - di - n - propyl S - b  - piperidinoethyl phosphorothiolothionate and O - ethyl O1 - n - propyl S - b  - diethylaminoethyl phosphorothiolothionate.ALSO:A combined plant nutrient and pesticidal composition comprises an acid addition salt of a phosphorothiolothionic ester of the formula S= P(OR1) (OR2)-S-LX, wherein R1 and R2 are alkyl radicals, L is a saturated aliphatic hydrocarbon radical in which the carbon atoms may be interrupted by an oxygen atom, a sulphur atom of an N-alkyl substituent, and X represents a salt of a secondary aliphatic or heteroyclic amino radical attached to L through the amine nitrogen atom, said nitrogen atom not being attached to the same carbon atom as the sulphur atom linking L with the phosphorus atom, together with a plant nutrient and, if desired, a solid or liquid carrier and/or an auxiliary agent.  Specified addition acids are hydrochloric, oxalic and para-toluenesulphonic acids.  Specified plant nutrients are urea and magnesium sulphate.  Specified carriers are water, nonphytocidal organic solvents, talc, kieselguhr, bentonite, other colloidal clays and powdered chalk.  Specified auxiliary agents are spindle oil, glycerol, wool fat, sodium dinaphthylmethane disulphonate, sodium lauryl sulphate,glue and resin.ALSO:A pesticidal composition comprises an acid addition salt of a phosphorothiolothionic ester of the formula S=P(OR1)(OR2)-S-LX, wherein R1 and R2 are alkyl radicals, L is a saturated aliphatic hydrocarbon radical in which the carbon atoms may be interrupted by an oxygen atom, a sulphur atom or an N-Alkyl substituent, and X represents a salt of a secondary aliphatic or heterocyclic amino radical attached to L through the amine nitrogen atom, said nitrogen atom not being attached to the same carbon atom as the sulphur atom linking L with the phosphorus atom, together with a solid or liquid carrier and, if desired, an auxiliary agent and/or a plant nutrient.
